Agronomics of New Potato Cultivars (1999) - 3 pages
New Cultivars tested;
ND2937-3 is a newly released very dark red-skinned variety under exclusive Canadian licence to
the Saskatchewan Seed Potato Growers’ Association.
Umatilla a new release from the Idaho breeding program, this Russet skinned potato is believed
to have superior processing and disease resistance characteristics.
Gem Russet A new release from the Oregon breeding program, this Russet skinned potato is
believed to have better yields and processing characteristics than Russet Burbank.
The 1999 growing season was cooler and wetter than normal from May through July. Little
supplemental irrigation was required until mid-August. Frost killed the vines in early September, just prior to the 120 days harvest. Yields under irrigation only marginally exceed those for the dryland trials. For many of the cultivars, there was little increase in yields from the 90 through to the 120-day harvest. In the dryland trials, this could be attributed to late-season moisture stress. The lack of yield increase
with time in the irrigated trial was unexpected.
